Manage HTML output generated by DartDoc for flutter project

[sandeep goyal]

I'm using "categories" in dartdoc_options.yaml, and able to generate the document and can see the categories under the "Topics" in HTML output.

Now, my aim is to ONLY display the categories shown under "TOPICS", not the each and every dart files under "Libraries".

1. Is it possible to not display each and every dart files under "Libraries".? if so, Please help me.
2. Is there any way to rename "TOPICS"?
3. Any other suggestions?

dartdoc_options.yaml is:

dartdoc:
categories:
"HomePageWeather":
markdown: doc/First.md
name: HomePageWeather
"WeatherSearchPage":
markdown: doc/Second.md
name: WeatherSearchPage
categoryOrder: ["HomePageWeather", "WeatherSearchPage"]
showUndocumentedCategories: true
